How to Choose a Ceramic Vacuum Feedthrough: The Complete Selection Guide
.JPG)
What Is Ceramic Vacuum Feedthrough? The ceramic vacuum feedthrough is a ceramic to metal seals components, it is a ‘feedthrough’ hermetic connector that allows electrical power, signals, motion, or fluids to safely pass through the wall of a vacuum chamber. It uses 95% alumina ceramic as an insulator to achieve vacuum sealing, and is a critical component in many vacuum devices. It is widely used in: Semiconductor equipment Vacuum chambers High-voltage systems Plasma and ion beam applications Step-by-Step Feedthrough Selection Guide 1. Define Voltage Requirement (kV) Up to 10kV → standard applications Up to 12kV+ → high voltage systems Example: If you are searching for 12kV high voltage vacuum feedthrough CF flange→ consider 8 Pin 12kV models 2. Determine Current (Amps) Multi-pin → lower current per pin Fewer pins → higher current capacity Example: Need 30A high current → choo...
